e-MS Composit Hornet > X3D Maingear and conical gear mesh

Hi again

Ok, I know I'm starting bothering ppl by posting way too much here but I'm afraid I'm developing the hate hornet syndrome - already took some valiums but that didn't help.

After a mild crash (broken blade, one link and mainshaft bent) I took as a personal objective to make this thing fly whatever the cost (yeah, this thing already surpassed the price of my evo 50).

Today I was fitting the maingear and I noticed the tail conical gear doesn't mesh properly. I'm sure it meshed before the crash so I replaced the conical gear even if it didn't look bad (had some scratches on it) and the mesh problem persists. if I turn the maingear and hold the tail, I can hear the teeth slipping. I also found out that if I apply a litte upward force on the tail, it will mesh perfectly with the maingear. Seems the maingear is lower than it should be but I already checked and there is nothing wrong here.

Don't tell me I twisted the E601 frame somehow sending the tailshaft higher than the maingear and now it doesn't mesh properly.

Note I have the X3D maingear (double one way bearing) and the E316 clutch sleeve which is the one that determines the distance of the maingear to the lower mainshaft bearing. I doubt that it got longer over night.

Any help on how to mesh those gears right? Short the clutch sleeve? put some material over the tail boom shaft so the angle in the frames is steeper down?

Thx
Tony

This one is new to me. Are you sure the 2 frames are still well attached to each other? If it were a carbon tail drive shaft I'd say check that too to see if the resin had shattered. But I really don't think you should be able to flex the frame/boom at all.

Man I wish you where right.

Tail boom is strait as an arrow. No material missing whatsoever. Conical gear is new. Upper teeth from the maingear are perfect. When I attach the main gear to the main mast the clutch sleeve goes up until it hits the lower bearing so that should give the exact distance between main gear and upper frame E601. I then insert the tailboom into the frame and I notice that only the last 2 mm of the conical gear touch the mainframe thats why it probably slips. When you grab the tail boom and pull it upwards the conical gear lowers a tiny bit and meshes with the main gear.

Could it be that the maingear somehow got lower on the clutch sleave? going to check that now. I'm also going to insert the mainshaft from the bottom up... I'm for anything right now.

Thx Captain Chaos, seems you're the expert around this part of the board. Thank you for your input

> After a mild crash
Sadly the X3D is not designed well for crashing, designed light.

Seems like... either the frame is deformed from square
or the lower shaft bearing is not seating correctly in the body
or the main shaft is snagging the lower bearing in some way.

EDIT: for the short term, try packing the frame space to push the boom, pinion and conical together.

Ah hah! The brainwashing is begining to take effect. Soon you will all believe that I am "Master of the Universe" and you all will become my puppets.

In truth I'd have to say that Jiri and DarkHorse1 and a number of others have been tinkering with these Hornets longer than have. I know Jiri has at least a years worth more experience and knowledge than I, and by the looks of things, DarkHorse1 may have at least that if not more dating all the way back to the H1 days?
----------------------------------------------------------------------------------------------------------

So did they change the X3D upper frame different from the H2 upper frame? I thought that one part was always the same from H1 to X3D. (see I only have experience with the H2.. and I didn't get deep into the fp Piccolos before giving them up, I should have played more with gearing on those I think).

LOL

na it's just brain cell storming, dump a few half backed ideas
and something might happen principle. Hey I was born a bodger

.

I've only really seen the x-series frames but I thought they were
similar if not the same in the area we are looking at

Well I'm out of ideas.

Yes, the X3D wasn't designed for crashing but that was also my first crash ever with any of my birds. If I knew those little beasts were so reactive I wouldn't let me distract like I did.

About the problem, if I fit a little piece of paper between the tailboom and the frame it will mesh correctly so either the frame become distored (can't tell and I have already inspected it for the last 4 hours) or somehow the maingear went lower. The only way to lower the maingear is if the oneway bearing go somehow higher.

Anyway, enough is enough.
A duzi axi maingear and a new E601 Frame is on its way. One or both will fix that.

Does anybody know if the duzi gear uses the bottom pin hole to lock to the main mast? If thats the case I have to get some 1mm carbon rod for that because I need a breaking point somewhere for the next "event"

Cheers
Tony

Hi

Yeah well mecanically the bird is ok (seems the problem was the original maingear) but I still havn't figured out how to setup the ccpm... I'm having problems with the elevator servo moving slower than the other two.. this didn't happen on the stock swashplate and servo positions.

I think I was never so fed up with a heli... if anybody wants a never flown (since total upgrade) X3D with all Duzi upgrades in the book let me know

Tony

Have you tried pushing up on the main gear, and then locking it in place with the shaft collar/ stopper ring /E067?

That seemed to work on mine, of course if you get it too tight, then it may strip.
